The value and versatility of projectors and other projection equipment was highlighted this week when a number of ad hoc temporary projection screens were erected around the country to display the televised funeral of Baroness Thatcher, who died last week.

Crowds of people – whether supporters, opponents or the merely inquisitive – gathered round projection screens that had been put up in locations that were significant in the life of Margaret Thatcher.

More than 50 students at the former Prime Minister’s old college at Oxford, Somerville College, watched the live transmission of the funeral procession and ceremony in London from the hall of their college, where a projector and screen had been arranged to make an impromptu cinema.

And in Baroness Thatcher’s home town of Grantham in Lincolnshire, local supporters gathered inside Grantham Museum to watch the ceremony and pay their own respects to the UK’s first – and only – female Prime Minister. Around 30 people gathered at the museum – although some observers did comment that members of the media did seem to outnumber members of the public at the event.

Baroness Thatcher died last week at the age of 87, after suffering a stroke, having suffered deteriorating health in recent years.
